Abstract
Currently, special attention is paid to the aircraft fuel quality as a component of safety to ensure trouble-free operation of the fuel system. The existing system of quality control involves periodic sampling of the fuel in the container and their subsequent control by the normalized quality indicators that do not identify possible reasons for the deterioration of these indicators to remove them for trouble-free operation and do not identify the factors of pollution sources. The monitoring system generally ensures the implementation of measures to preserve the quality of aviation fuel and flight safety of serviced civil aviation airlines at current level according to regulatory requirements. The article describes the mathematical model for calculation parameters of indicator filtering partitions based on cascade filtration theoretical studies of mechanical impurities. Pores of indicator filtering partitions calculated by means of mathematical model have been experimentally tested on simulator stand and showed a good convergence of calculated and experimental results. The use of cascade filtration of fuel with different indicator partitions parameters made it possible to develop a device for fuel purity monitoring, allowing continuous (inline) monitoring the level of liquid flow contamination at various points of technological equipment (for example, after the pump, at the inlet and outlet of tanks and units, the output of the filter, etc.) and to carry out functional diagnostics of units condition process equipment by monitoring changes of particle parameters and the wear occurrence.
Highlights
The research determines the problems of pilot studies to assess the adequacy of the results of simulation in simulators operators of radio electronic equipment for air traffic control
Hardware requirements to conduct flight experiments to assess the adequacy of training facilities by members of the flight management group for air traffic control in the near field zone are formulated
For the probabilistic assessment of simulation adequacy in training facility radio electronic means (REM) operators the generalized criterion "Fisher - Chi-square" is selected, which allows to obtain the updated value of the significance level using the Fisher criterion, and based on this, using the goodness of fit Chi-square to produce a quantitative assessment of the adequacy of the simulation in the training facility radio electronic equipment
Summary
Определены проблемы реализации экспериментальных исследований по оценке адекватности результатов имитационного моделирования в тренажерах операторов радиоэлектронных средств управления воздушным движением (РЭС УВД). Для вероятностной оценки степени адекватности имитационного моделирования в тренажерах операторов радиоэлектронных средств (РЭС) выбран обобщенный критерий Фишера-χ2, который позволяет по критерию Фишера получить уточненное значение уровня значимости, а на основании этого по критерию согласия χ2 произвести количественную оценку адекватности имитационного моделирования в тренажерах РЭС. В целях повышения качества тренажной подготовки лиц ГРП и приближения процессов, моделируемых в тренажных средствах при УВД в ближней зоне аэродрома к реальным, предложен метод для оценки адекватности результатов имитационного моделирования в тренажерах операторов РЭС УВД на базе летного эксперимента. Метод оценки адекватности имитационного моделирования в тренажерах операторов радиоэлектронных средств на базе летного эксперимента рассмотрим на примере тренажных средств операторов управления воздушным движением (УВД) лиц ГРП
